【摘要】 低速性能是直接转矩控制（ＤＴＣ）方法的瓶颈，其中死区效应是一个很重要的影响因素．关于死区分析、补偿的文章有很多，但在分析或实现上较繁琐．本文对死区效应的影响进行了分析与仿真，并提出一种新的软件补偿方法，仿真结果证明了该方法的有效性。更多还原

【Abstract】 Low-speed performance is a bottleneck of direct torque control (DTC) method. Dead-time effect is a primary factor. To compensate the deadtime effect, some methods have been proposed, but they are often too complicated or need additional hardware. In this paper, the dead-time effect is analysed and simulated and a new software compensation method is presented. Simulation results confirm the validity of the method.更多还原
